How to Save the World: new tax system

Ok, it looks simple but I couldn't help thinking "it makes a lot of sense!" when I read the details.

Now which countries, or cluster of nations, would be the most likely to walk down that path? I personally  would love to see Europe takes the leadership and move down that direction. Europe built up a kind of collaborative governance that could be a model .... Maybe with more spirit, heart and humanity... Or perhaps, Canada with its environment friendly attitude could spear-head a way?

I came to this article from another article from Dave Pollard, that lays down a roadmap to achieve sustainable economy. Looks like a right-on constitution to me, no?
